This paper presents the design and engineering realization of FPD（Flat Panel Display） scanning controller based on the fractal IP core. The fractal scanning controller can he used in FPDs such as LED, OLED, TFT-LCD and so on. The FPD system is made up of the multimedia video card, the Ethernet video transmitter unit, the fractal scanning controller and the LED flat panel display. Using the fast Ethernet agreement technique to substitute the traditional dif- ference data transfer method obtained the advantages such as fast speed, long distance data trans-mission and the high reliability of transceiving data. The novel controller was implemented with FPGA which can efficiently increase the imaging gray scales and quality. The completed LED system verified the feasibility of the fractal scanning controller applied in FPD industry and its contribution to boost the frame rate and gray scale in FPD system.
